Abstract
The utility model relates to a gun drill hung type hand-tight drill chuck with a handle, which comprises a chuck body, clamping legs which are inserted into oblique holes at the front of the chuck body, internal tapered nuts which are in threaded fit with the upper parts of the clamping legs, a front shell, and a back shell of which the wall surface of an inner hole is provided with a locking step, wherein the spacing distance between a front retaining ring and a back retaining ring which are arranged on the external diameter of the back of the chuck body allows the drill chuck to be hung on a conversion support on a multi-bit gun drill for conversion, and a lateral pin which is arranged at the inner end of a central hole of the chuck body can be matched with a cross nick arranged at the front end of a spindle of the gun drill. The gun drill hung type hand-tight drill chuck with the handle is convenient and quick to assemble and disassemble, and has a reasonable structure.
Description
Technical field
The utility model relates to the used drill chuck of a kind of hand-held The Multicipital Rifle Drill, especially a kind of can being applicable on the The Multicipital Rifle Drill of being with the drilling tool conversion device structure for hanging the band handle drill chuck that conversion is used.
Background technology
Existing drill gun drill chuck, can only be fixed on single use on the drill gun main shaft, repeatedly tool operation such as clamping drill bit trouble, effort repeatedly, especially during work high above the ground since the transposing drill bit accidentally drill bit is fallen down, go to seek inconvenient again, even fall down and lead to a disaster, people need design a kind of supporting use that can be full of The Multicipital Rifle Drill for the drill chuck that hangs on The Multicipital Rifle Drill for this reason.
Summary of the invention
The purpose of the utility model is to disclose a kind of original clamping function of drill chuck that both kept to society, can be suspended on the drilling tool conversion equipment of drill gun the band handle drill chuck that also can mount and dismount easily at any time again.
It is such that the utility model solves the technical scheme that above technical problem takes:
Be used for clamping the clamping structure of instruments such as drill bit: the front portion is provided with three inclined holes, the collet body of rear portion band medium pore, insert three pinches in anterior three inclined holes of collet body, interior flare nut with pinch top threaded engagement, plane bearing is sleeved on the collet body, and with the tight cover of interior flare nut and interior flare nut is embedded in procapsid in the groove of collet body, the procapsid back is a back casing, the back casing front end has spring, and back casing has preceding ring washer to block; The relatively rotating of procapsid and back casing can make three pinches stretch in inclined hole and clamp the clamping structure of instruments such as drill bit.
Can supply the band handle structure of suspension: the collet body rearward end is embedded with the back back-up ring, and spaced distance between preceding back-up ring and the back back-up ring can be for being suspended on the conversion support, and this spacing distance partly is exactly to be with handle structure.
Latch-up structure: the steel ball that is shaped on the endoporus wall of back casing in the through hole that the locking step that is high and low and collet body rear portion external diameter communicate with medium pore is formed latch-up structure, described collet body rear portion is shaped on middle folder hole, the through hole that external diameter is shaped on the symmetrical parallel plane and communicates with medium pore, through hole is greater than diameter of the steel ball, but near the aperture of medium pore wall less than the diameter of steel ball in case fall down, be placed with two steel balls in the through hole, part is exposed on wall surface of the hole; The parallel plane that back casing endoporus wall is shaped on symmetry is sleeved on the symmetrical parallel plane of collet body external diameter, and back casing utilizes the two parallel plane to cooperate the synchronous rotation of drive collet body can pass on external diameter again; The back casing that is shaped on the locking step is manually passed when ending terminal point, the position, space appears in the top of steel ball, expose under the thrusting action of the drill gun main shaft of the steel ball on the central hole wall in the hole and be pressed against the position, space, so main shaft can spur arbitrarily, as stop moving to back casing, back casing is homing under the spring action of front end, the low level extruding steel ball that locks step simultaneously is in the hole, and make exposed again steel ball on the central hole wall of the other end of through hole, as embedding groove on the drill gun main shaft, drill chuck is locked no longer to be moved axially.
Syndeton with the drill gun main shaft: collet body medium pore inner end is provided with fixing lateral pin, can match with " ten " word breach of drill gun front-end of spindle, so that be driven to rotate.
The utility model is because said textural association above using can supportingly hang for the conversion use and connection on main shaft, installation, convenient disassembly on the The Multicipital Rifle Drill of band drilling tool conversion equipment.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structure cutaway view of the present utility model.
Fig. 2 is the cutaway view of Figure 1A-A.
Fig. 3 is the cutaway view of Figure 1B-B.
Fig. 4 is the schematic diagram of drill gun main shaft.
Among the figure 1, pinch 2, collet body 21, lateral pin 22, medium pore 3, interior flare nut 4, procapsid 5, plane bearing 6, spring 7, back casing 71, locking step 8, preceding back-up ring 9, steel ball 10, back back-up ring
The specific embodiment
In Fig. 1 at the medium pore of collet body, back-up ring 8 and back back-up ring 10 before the external diameter at rear portion is provided with, spaced distance between them, pulling down the back back-up ring can insert band handle one end of drill chuck in the bracket holes of drilling tool conversion equipment, and then buckle into the back back-up ring, so conversion use when just being suspended on the support for work; When rotating back casing 7, and procapsid 4 is motionless relatively, back casing relies on the symmetrical parallel plane that cooperatively interacts to drive collet body 2 and rotates, three pinches 1 of collet body front portion are under the effect that is in static interior flare nut, be forced to move as axial stretching, because three pinches are to be inlaid in the inclined hole, therefore the telescopic moving of three pinches becomes clamping radially or unclamps; Back casing 7 can not only start above-mentioned functions, we can also make this drill chuck at the locking action on the drill gun main shaft: when need install drill chuck, the drill chuck endoporus is aimed at the drill gun main shaft to be advanced inwards, withhold simultaneously pass drill chuck back casing (7) to terminal, the position, space appears in the locking step 71 that at this moment is height above corresponding steel ball, because main shaft is to exposing the pushing tow of steel ball on hole wall (9) in progradation, so steel ball is pressed against the position, space, at this moment drill chuck advances smoothly inwards, stop the to withhold passing of hand simultaneously to back casing, under the effect of spring the locking step get back to original position simultaneously the low level of step push steel ball again and in through hole, move, embed until steel ball on the wall that exposes at medium pore in the main shaft groove of drill gun, meanwhile the lateral pin 21 of collet body medium pore inner end embeds " ten " word breach of drill gun front-end of spindle, as press the drill gun switch, this drill chuck just is driven to rotate, inverse operation process, just detachable drill chuck.
